Energy consumption for products of lithium salt
1 Scope
This document stipulates the requirements, statistical scope, calculation method,
calculation scope, energy-saving management and measures for the energy
consumption per unit product of lithium salt (hereinafter referred to as energy
consumption) limits.
This document is applicable to the calculation and assessment of product energy
consumption of manufacturers, that use spodumene concentrate, lepidolite concentrate,
brine as raw materials to produce lithium salts, such as lithium hydroxide, lithium
carbonate or lithium chloride, as well as the energy consumption control of newly built
projects.
2 Normative references
The contents of the following documents constitute essential provisions of this
document through normative references in the text. Among them, for dated reference
documents, only the version corresponding to the date applies to this document; for
undated reference documents, the latest version (including all amendments) applies to
this document.
GB/T 2589 General principles for calculation of the comprehensive energy
consumption
GB 17167 General principle for equipping and managing of the measuring
instrument of energy in organization of energy using
3 Terms and definitions
The terms and definitions as defined in GB/T 2589, as well as the following terms and
definitions, apply to this document.
3.1
Unit energy consumption in working procedure
The energy consumed by the production enterprise to produce qualified products
during the production technology.
3.2
EZG - Energy consumption of various product technology;
EZF - Energy consumption and losses in indirect auxiliary production departments;
EZZ - Comprehensive energy consumption of all products.
All types of energy consumed shall not be recalculated or omitted. Where there is a
supply and demand relationship, the input and output parties shall be consistent in the
calculated values. The energy consumption of equipment shutdown and overhaul shall
also be included in the calculation; meanwhile it shall be evenly distributed on a
monthly basis, according to the operation cycle of the equipment after the overhaul.
The comprehensive energy consumption of enterprises is calculated in accordance with
the provisions of GB/T 2589.
Note: The energy consumption planed by the enterprise during the reporting period refers to the
energy consumption directly used for production during the statistical period of this plan.
5.1.3 Measurement of physical energy amount
The measurement of physical energy amount shall comply with the Measurement Law
of the People's Republic of China and GB 17167.
5.1.4 Measurement units of various energy sources
The units of enterprise production energy consumption, product technology energy
consumption (or product direct comprehensive energy consumption), product
comprehensive energy consumption: kgce, tce (kilogram standard coal, ton standard
coal);
Units of coal, coke, heavy oil: t, 104 t (ton, 10000 tons);
Units of electricity: kW·h, 104 kW·h (kilowatt hours, ten thousand kilowatt hours);
Units of steam: kg, t or kJ, GJ (kilogram, ton or kilojoule, million kilojoules);
Units of gas, compressed air, oxygen: m3, 104 m3 (cubic meters, 10000 cubic meters);
Units of water: t, 104 t (ton, 10000 tons).
5.1.5 Methods for converting various energy sources (including energy consumed
in the production of energy-consuming working fluids) into standard coal amount
The application of energy with a low (bit) calorific value equal to 29.3076 MJ
(megajoules) is called 1 kg of standard coal.
For externally purchased energy, the actual measured low (bit) calorific value or the
actual measured value provided by the supplier can be used as the basis for calculation,
OR it can be converted using the conversion coefficient of the national statistics
department, as shown in Appendix A. Secondary energy and energy-consuming
working fluids are converted according to the corresponding energy equivalent value:
when the enterprise converts energy to self-production, the amount of standard coal is
converted according to the actual physical amount of energy input; when it is sold and
supplied by a centralized production enterprise, its energy equivalent value shall be as
specified by the competent authority; when it is purchased or sold, the energy equivalent
values shall be the same; when the energy equivalent values are not provided, they can
be converted according to the conversion coefficient of the national statistics
department, as shown in Appendix B. The waste heat recovered by the enterprise is
based on the conversion coefficient of heat; the waste heat power generation is
uniformly based on the conversion coefficient of electricity.
5.1.6 Determination of product output per unit product energy consumption
To calculate the product output of lithium salt per unit product energy consumption, it
shall use the output of qualified lithium salt within the same planned reporting period.
All product outputs are based on data, which is officially reported by the enterprise
planning and statistics department.
5.1.7 Calculation principles for energy consumption in waste heat utilization
The waste heat recovered by the enterprise belongs to energy saving and recycling; it
does not belong to purchased energy. When calculating energy, it shall avoid double
counting with purchased energy. The energy used by the waste heat recovery device is
included in the energy consumption of the technology or procedure. The heat or power
generation recovered from waste heat in each technology or procedure shall be deducted,
if it is output to this technology or procedure. If the recovered heat or power generation
is consumed or used in this technology or procedure, there shall be no energy
consumption deduction in this technology or procedure. The amount of waste heat
recovery deducted shall not be double-counted. When it is supplied to other procedure,
it shall be included in the normal energy consumption in the technology used. The
recovered energy shall be deducted in the procedure and technology of recovering waste
heat, after being converted into standard coal. If the energy consumption indicator for
waste heat recovery has not been deducted, it shall be marked as “Waste heat recovery
energy has not been deducted”.
5.1.8 Others
Indirect comprehensive energy consumption includes: a) The energy consumption of
indirect assistant and auxiliary production systems; b) the loss of energy and energy-
consuming working fluids in the internal storage, conversion, distribution, supply, sale
of the enterprise, shall be distributed to each product, according to the ratio -...
